Abstract: L'invention concerne des polymères dendritiques à amplification et fonctionnalité intérieure améliorées. Ces polymères dendritiques sont obtenus par la mise en oeuvre de réactions chimiques rapides à ouverture de cycle (ou d'autres réactions rapides), combinées à l'utilisation contrôlée de réactifs à cellules ramifiées en vue de former rapidement et précisément des structures de dendrimères, génération par génération, aux structures précises, à l'aide de procédés chimiques plus propres, généralement des produits uniques; lesdites réactions produisent moins d'excédents de réactifs, utilisent des taux de dilution plus faibles et un procédé à capacité de rendement supérieure, permettent de passer plus facilement à l'échelle commerciale et d'obtenir de nouvelles gammes de matières à moindre coût. La composition de dendrimère préparée comporte une nouvelle fonctionnalité interne, une stabilité supérieure, p. ex. stabilité thermique et peu ou pas de réaction de Michaels inverse, et permet d'atteindre des densités de surface d'encapsulation à de moindres générations. De façon inattendue, les réactions entre réactifs polyfonctionnels à cellules ramifiées et surfaces polyfonctionnelles ne produisent pas de matières gélifiées. Les polymères dendritiques sont utiles comme agents désémulsionnants pour émulsions huile/eau, agents conférant une résistance au papier à l'état humide, éliminateurs de protons, normes d'étalonnage en microscopie électronique, pour la fabrication de membranes sélectives par rapport à la taille et comme agents modifiant la viscosité dans des formulations aqueuses telles que la peinture. Lorsque ces polymères dendritiques portent une matière associée à leur surface et/ou à l'intérieur de ceux-ci, ils possèdent des propriétés supplémentaires dues aux caractéristiques uniques du polymère dendritique.

Title: Switching voltage regulator with low current trickle mode
Inventor: VINN CHARLES
IPC: G05F1/10
Filed: 2007-02-02
Granted: 2009-09-08
Abstract: For load currents greater than a threshold current, the voltage regulator operates in a conventional manner by fully turning on and off one or more switching transistors (16) at a duty cycle necessary to maintain the output voltage a regulated voltage. Upon a load current below a threshold being detected (76), a controller stops the switching of the transistor(s) and applies a reduced drive signal (44) to the high side transistor so as to apply a constant trickle current to the load. Unnecessary components are shut down to save power (42).  When the output voltage falls below a threshold (46), the normal switching routine is resumed to recharge the regulator's output capacitor (28) to a certain level, and the regulator once again enters the light load current mode. By not completely shutting down the transistors at light load currents, as in done in a conventional intermittent-operation mode, there is lower power loss by less frequent switching of the transistor(s).

Title: Mobile object information sharing system
Inventor: IJIRI MASAO
IPC: H04W64/00
Filed: 2005-04-07
Granted: 2012-12-18
Abstract: In a system where mobile stations use one frequency to transmit/receive and share the data, synchronization has been made in a shared time resulting from GPS and the mobile stations transmit the data at mutually different timings that are predetermined, whereby overlapping of the transmissions is avoided. However, the transmission period of a station cannot be changed even if that station wants to change its transmission period. Transmission period determining units are disposed which determine transmission periods on the basis of the moving speeds of mobile stations. The mobile stations are time-synchronized by GPS. After the time synchronization, fundamental transmission periods comprising plural time slots are disposed. Transmission is done just in one time slot within one fundamental transmission period normally, and the number of transmissions is increased to two times or three times within one fundamental transmission period when the period is to be shortened.

Granted: 2011-12-06
Abstract: A technique distributes localized stress acting on a tubular. The tubular is formed with an inner layer and an outer layer that is compliant relative to the inner layer. A force distribution material is disposed between the inner layer and the outer layer to spread any concentrated loads acting against the tubular. The compliant nature of the outer layer causes it to distort against the force distribution material when acted on by a concentrated external load. The outer compliant layer and the force distribution material cooperate to isolate and protect the inner layer from displacements of the surrounding subterranean material.

Abstract: An underreamer for well drilling comprises pivotally extendible roller cutters that extend slightly beyond the diameter of the pilot drill bit but are retained in their retracted position by the casing. Upon encountering an obstruction, the underreamer is pushed out of the casing, allowing the outer edges of the cutters to contact the obstruction. Continued downward pressure of the drill stem causes the roller arms to pivot outward to a fully extended position in which the cutters enlarge the hole to a diameter larger than the casing by rotation of the drilling stem. The advance of the casing relative to the underreamer forces the cutters to retract into the casing.
